Polygon is a simple closed curve which is made by only line segments. We can classify the polygons according to the number of sides or vertices they have and also classify them based on their properties. The sum of interior angles of n-sided polygon is (n-2) × 2 right angles. Diagonal is a line segment which connects non adjacent vertex of polygons. Q-2(a)- Find the number of diagonals in 15-sided polygon. (1 mark) Q-2(b)- Which of the following figures are polygon?
